I was thinking of something aligned with the divine if I go for father Luc, and something that doesn't require him to have a lab at all.
What about this small iteration on the concept:
- True Faith and Banishing (from HoH:S, p.118), + Magic Sensitivity and Premonitions (all aligned with the Divine).
- Banishing gives him the ability to banish (Realm) creatures from a certain area for Sun duration. Not as good as a good Rego specialist, but can still shine when required.
Story flaw Plagued by Supernatural (some faerie creature around the village, that he has managed to keep away... until now, at least).
This is assuming we want our village priest to be more present in covenant affairs. There is nothing wrong with him being just a regular priest. ^^
